An apparatus includes: a fixed primary anchoring element, a beam mount movably connected to the primary anchoring element, a beam connected to the beam mount, a vessel mount movably connected to the beam, a vessel connected to the vessel mount, the vessel being movable along at least a vertical axis, and a control unit within the vessel. The control unit is configured to accept control input from a passenger within the vessel and transmit at least one control signal to cause the beam to move relative to the primary anchoring element, the vessel mount to move relative to the beam, and the vessel to move relative to the vessel mount independently.
